being hydrophobic and making up substances such as fats‚ oils‚ and waxes in many forms that provide various benefits to all organisms who need them. Lipids are made out of two main elements: carbon and hydrogen‚ while being consisted of fatty acids‚ glycerol‚ etc. The four main groups in which lipid molecules are classified are: fats‚ phospholipids‚ waxes‚ and

Proteins on the other hand can be reduced into amino acids and fats can be reduced to fatty acids and glycerol. The smallest forms of the usable nutrients pass through the walls of the small intestine

a series of tests were ran. Tested were the biomolecules of cells which are lipids‚ sugars‚ proteins and starch. The purpose of these tests were to test for the presences of cellular biomolecules. Some of the things that fat consist of are one glycerol and three fatty acids. Proteins are considered polymers. They are made up of smaller molecules called subunits. Now with proteins they contain a large number of amino acids that are joined together by a peptide bond. With the starches‚ they contain

This means that cells which are not viable would not take up the dye and due to their age and not their ability to break down the

Similarities and Differences Bacteria and archaea both share the fact that they are single-celled prokaryotic microorganisms that lack membrane enclosed nuclei. It has been discovered that the two typically can be found to have the same size and shape as one another. “They are both found occurring as rods‚ cocci‚ spirals‚ plates‚ coiled etc.” ("Archaea vs. Bacteria‚" n.d.). Both organisms use the flagella to swim and also reproduce by means of binary fission. On the surface these similarities can

Proton‚ Electron and Neutron 2) Which Subatomic particle is most important to biological systems? The most important subatomic particle to biological systems is 3) Be able to indentify various Chemicals bonds. 4) How does polarity of water make it an excellent solvent? The polarity of water is caused by the electro negativity of the oxygen atom‚ so electron density is

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

SCIENCE - FORM 2 Nutrition CLASSES OF FOOD 1. Food is a basic necessity for all living things. 2. Food is important in order to : (a) Provide energy to carry out physical activities. (b) Provide energy for the physiological activities in life such as reproduction‚ digestion and excretion. (c) Build new cells and ti repair tissues in the body.
